[Solved] Menu is doing full postback with opening windows

[Marco]

Hello,

I have a menu that is opening different windows, or opening pages in a targeted RadPane.
Both of this worked ok in the standard RadControl menu.

But now when i set a window opener like this:

wndMessages.OpenerElementID = RadMenu1.Items(0).Items(0).ClientID

The window is not opened, but instead the menu gives a full postback.
 Is there something changed here?

Thanks

Hi Marco,

The most probable cause is that RadMenu "Prometheus" does not render IDs for the menu items in order to reduce the output size. Can you please send us a simple project, so we can try to find a workaround for the issue?

That can be the cause, after looking in the generated html. (no id's)
But the windowopener line, is giving a Clientid like 'Radmenu1_i0_i0'..

If i can find some time, i will make a sample project, and send it to you.
For the moment, i have roll back to the standard menu radcontrol.
(this is a big application, where i can not do without this functionality)

Thanks anyway

Hello Marco,

We have found an easy workaround that you can try. You can use custom attributes to render the id. The code should look like this:

private void Page_Load(object sender, EventArgs e)
{
    foreach (RadMenuItem item in RadMenu1.GetAllItems())
    {
        item.Attributes["id"] = item.ClientID;
    }
}

The windows are working good now with the Prometheus menu.

For vb.net i changed this in:

Dim item As RadMenuItem
For Each item In RadMenu1.GetAllItems
     item.Attributes("id") = item.ClientID
Next

Thank you for the solution.
